MINI-BASIC is a Window Console Basic interpreter using Windows API to manage display, keyboard and files. MBI.ZIP includes executable MINI-BASIC, complete SOURCE listing in MASM assembler, MINI-BASIC user's guide and PITMAN, a special Basic game for MINI-BASIC.

Although Mini-Basic works fine, it may be considered as a toy to play with for newbies and experienced Assembly programmers, a piece of code available for modifications, enhancements, experiences and programming pleasure. Some problems are not totally solved (console window resizing for example).

Please, report bugs, enhancements, new commands, optimizations you add in MINI-BASIC.

New versions will be added to this page to keep MINI-BASIC alive.

MINI-BASIC was written with MASM32 tools available for free at http://www.masm32.com

There is also a Yahoo Group devoted exclusively to MINI-BASIC. That can be found below:

http://tech.groups.yahoo.com/group/minibasic/

Let me know if you're able to convert it from MASM to FASM.

Hi dunric76,

If you talking about this Mini-Basic i like the project and i've experimented a lot with it in MASM, i still do occasionally, trying to fully understand the code.
I've contact the author a couple of times in the past (are u him?)
It uses only 486 instructions and console api calls, but it's a bit outdated and there are some API issues which need to be fixed.
Yes, a FASM version would be nice.

Yardman's link is a powerful Basic interpreter, but 15000 code lines are beyond my potentials Very Happy

A FASM version, I believe, would have fewer errors. MINI-BASIC has some issues with sometimes crashing with strange Windows API errors. And sometimes the text formatting is a bit off, especially with printing integers to the screen.

I think it would be a nice project to convert it over to FASM, and make some changes so it doesn't crash.

RTFL ! You can maybe get MASM32 legally without explicitly paying for it, however, you must already have a paid OS from Macrosoft, and you may develop for paid "OS"'s from Macrosoft only (so restrict your users as well).

Yes ... but ... where's the problem? MBasic is a Win32 program, it runs on Windows. As far as Masm32 is concerned, there is absolutely no problem.

What might be an issue is that the MBasic source is copyrighted. That means, you cannot just convert the source to Fasm and make this new source publicly available.

How is this to be achieved? Some black magic?

Well, FASM seems more stable than MASM. I believe it would output better assembly. I've used FASM before while compiling HLA (High Level Assembly" language programs. It works well and uses POLINK.

Is this true? I know MASM has some failings but I never knew it spat out bad binary code. Which instructions does it get wrong?

not really "instruction", but at least it gets "invoke" wrong in some cases (word param in 32bit code, i think)

Errors in FASM are often fixed within hour. In other cases, you never wait more than few days.

The old "invoke" bug has reportedly been fixed in Masm v9.0. I didn't test myself, though.

Fasm users can now experiment with MINI-BASIC.
Note: No effort has been made to update the code or fix some IDE bugs.

Took a quick peek, no time now, but...

WTF?
Code:
STD_INPUT_HANDLE  EQU -10 ;Standard console input handle
STD_OUTPUT_HANDLE EQU -11 ;Standard console output handle    


WTF?
Code:
TestApiError:
    mov     DWORD PTR [MsgBoxText1], "API "
    cmp     eax, 0
    jz      Error
    ret
Error:
.data
MsgBoxCaption            DB "API Error",0
MsgBoxText               DB "Error "
MsgBoxText1              DB "    ", 0
.code
    invoke  MessageBox, 0, ADDR MsgBoxText, ADDR MsgBoxCaption, 0
    invoke  ExitProcess, 0

Well, these lines can be remarked or removed since handles already defined.

Picnic: The second WTF from bitshifter is because if fasm generates an .exe directly (without a linker) then you get the label "Error:" at then end of one section, then a new section with the API strings, then another new section with some more code. fasm doesn't combine sections, that is what linkers do. fasm just lays out the sections exactly as you present them.

So what will happen is that if the code ever gets to the "Error:" label you will get the code running wild executing unexpected code.

I understand, so it's advisable to keep all MINI-BASIC data in one section.

I think that would be advisable.

[edit] Actually more to the point is to combine all the code sections together.

How do you get a MBI file to load? It seems to be giving me some trouble by saying file not found. Though I made a separate folder for it.

Need more information.

Which file is not found? Please show the error that fasm reports.

Hi,
Recompile the source and try again. I did that just now and the PITMAN demo loaded ok. then type run.
